KNEADINGl-EVIACHINE.

SPECIFICATION forming part of Letters Patent No. 635,310, dated October24, 1899.

Application filed April 7, 1899. Serial No. 712,059. (No model.)

T0 @ZZ whom t may concern:

Beit known that I, CHRISTIAN FLEcK, a subject of the Emperor of Germany,residing at Oh'ligs, Germany, have invented certain new and usefulImprovements in Kneading- Machines, of which the followingis aspecification.

My invention consists of a tank or receptacle in which two shafts aresupported at opposite inclinations, and said shafts are provided withagitating-arms arranged in different horizontal planes and rotating withtheir respective shafts so that they cross each others paths, of apeculiarly-formed bottom for said tank, of giving a peculiar form to theagitating-arms and adapting them to travel in lines parallel to theaforesaid bottom, and in the provision of other details useful andnovel, as will be fully described.

In the accompanying drawings, forming a part of this application, Figurel is a vertical longitudinal section of my invention complete on acentral line. Fig. 2 is a vertical crosssection on line t' vl of Fig. l.Fig. 3 is a top plan view of the machine.

Referring to the drawings, A represents a tank or receptacle suitablymounted on a base M.

B and C represent, respectively, shafts set at an inclination towardeach other and located in the central longitudinal planeof the tank.Said shafts pass through and are guided at their lower parts in suitablebearings in the bottom D, and at their upper ends have bearings inopenings in a bar E, arranged transversely of the tank. The shafts B andC are rotated by a drive-shaft F, which is journaled in suitablebearings X X on the cross-bar E and has keyed to one end a iiy- Wheel Nand may be driven by hand or any suitable power. F is transmitted to theshafts B and O by means of a bevel gear-wheel G on the shaft F, G on theupper end of the shaft B, meshing with the gear G, and gear-wheels IIH', fixed on the lower ends of the shafts B and O, respectively, andhaving their teeth intermesh, whereby the shafts are rotated in oppositedirections.

Q represents a metal or other suitable casing, within which thegear-wheels G G' are housed.

The rotation of said shaft Each of the shafts B and O carries a seriesof agitating and kneading arms, preferably arranged in pairs and curved,as J and K. Said arms are arranged one above the other upon theirrespective shafts, so that the two series when rotated will cross eachothers paths between the shafts. Said arms are of such length that thearms of one series are brought close to the shaft of the second series,but without striking same, and are bent or curved convex to thedirection of rotation. The arms are arranged at such angles to theirrespective shafts that they travel in a horizontal plane and so that theupper arm of one series passes over the lower arm of the other series.

The bottom D is suitably secured to the walls of the tank and slopesdownwardly and inwardly toward the shafts B and C, while the portionbetween said shafts is horizontal.

The upper arm K of each series of agitators carries at its outer end anextension or blade L, set at an acute angle to said arm, said bladeserving to detach the paste from the shaft upon the rotation of the arm,whereby the paste is efectively prevented from being twisted around saidshaft.

A door M is provided in the front wall of the tank A, through the Way ofwhich the completed paste is removed from the tank. Said door maybelocked by means of a screw W or. its equivalent.

The apparatus above described is used by placing the materials to bekneaded into the tank and the arms rotated. The peculiar shape of thearms serves to drive the materials toward the walls of the tank, whilethe shape of the bottom D tends to throw them toward the center, thusthoroughly mixing and kneading the materials.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A kneading-machine comprising a tank, inclined shafts mounted in avertical plane in said tank, means for rotating said shafts in oppositedirections, a bottom having downwardly and inwardly inclined sidessecured to said tank, agitating-arms secured to said shafts and adaptedto rotate parallel with the said bottom, and provided withangularlyarranged extensions, as described.

IOO

shafts carrying on its upper end a bevel-pinion, a drive-shaft, abevel-pinion on said driveshaft and meshing with a like pinion on theinclined shaft, a bottom having downwardly and inwardlyT inclined sidesand horizontal central portion, arms secured to said shafts and curvedconvex to the direction of their movement, said arms being adapted torotate parallel to said bottom, and angular eXtensions on said arms,substantially as set forth.
